colorsanding/polishing paint... been a while

Years ago, I used to work in the automotive collision repair/refinishing industry, after graduating from WyoTech. I started working in the detail shop, and was responsible for colorsanding/buffing/polishing the paint on the cars after they had been painted.. (this was back in the early to mid 90's).. My process back then was to start with 1500 grit, then 2000 grit, then using a rotary buffer with a coarse pad and cutting compound - then a finer pad with a polishing compound, then a black foam polishing pad with a very fine polishing compound, then a nice glaze..

I know things have changed a lot since then.. there are finer sandpapers available now, there are better buffers available now (I have both a Makita rotary buffer as well as a Porter Cable DA polisher, which I haven't used yet) .. as well as different cutting/rubbing/polishing compounds...

So - I am looking to start the process of colorsanding/buffing the paint on my Dart - which was painted a year ago (yeah, I know.. the paint is going to be rock-hard).. it was painted with Omni single stage. There's a fair amount of orange peel as well as a few fish-eyes.. no runs, thankfully. I'm not worried about making the paint flat, as it would just make the bodywork look worse (it was a budget-minded paint job.. the bodywork is ok, but not great).. I simply want to cut down some of the texture as well as any of the pieces of dirt/dust in the paint so it's smoother.

My thoughts are to do a 'quick nib' with 1500 wet, to take care of the pieces of dirt/dust in the paint.. then go over more of it with 2000 to take out the 1500 scratches, and take down some of the texture.. then 2500 after that.. pretty much only from the mid-line of the car, up to the top surfaces.. no point in colorsanding/polishing the lower half of the car, as far as I'm concerned.

So then the question is .. should I just do what I know, and use the rotary buffer to remove the 2500 grit sandscratches, and then polish it - or should I use the Porter Cable? I really don't want to burn through any edges.. it's been a number of years since I've colorsanded/polished a car.. so I know that I won't be as good at is as I used to be..

What do you guys use (specific product recommendations would be great) for this process?

thanks
